[edit] Model numbers

On all models of the PS3, the last seven characters of the serial number make up the console's model number. This begins with "CECH", followed by a letter indicating what model the system is. The last two characters of the model number indicate what region the system is from. More detailed hardware information available at PlayStation 3 Secrets
